invention relates tinskylight. stnuc tures; and: the operation of. I the sections tor;

ventilation purposes-.1

One-oft the objects ofmy intention is the;

rovision. of? actuating mechanism for skylight sections-andsimilan useswhmh 1s very.

s1mple=iin construction; reliable; in .ope 'm t-io'n, capable of; quick: and easy installation and; inexpensive to 1 manufacture:

Funther objectskof my invention are-to provide a mechanism, that, will open vand close: hinged sections; 0111 either. side. of a. skylight and the like to any positiom'mt ermediate: of: closedqto open eitherv on one side on omboth s-ide's. I

7 Further objects? ot my invent1on. are;. to provide" a mechanism. that: Will perform its cycles-or. cycles of operationa; continual movement in. onedirectioh without jamming;

To atta-ini these objects I-use 1 acontinuious chaini mounted on sevenal sprockets; and

provide ameans for moving this 'chain' l around thesesprockets andithrough links connected to the chain and skylight. sash, I attainthe object off opening the sections at eitherrone on '3 both I sides? of: the skylight. In

Starting from: a, positionwhen both. sides of the skylight are closedgthe yarious parts are: shown asleft sash A; and link B; right hand sash D and link .G;.andfthe juncture of the twolinks at: the bottom: as Q.-, Assuming thatthe chain 6. is being. moved in counter-clockwise direction ior a part of. its POSSlblGftIZlVQLlZhG various, parts will take the positions, as shown by the lines 2 as ;-left"= hand sash A, and link E, right hand sash G,- and link; F,. and

the juncture of the bottom ends of the links aszR. The next movement of thenchain 6 Lcanbe-stopped tqresult inthe positions as;

left hand sash A, and link H, right handsash J v andlink Izand the juncture of the bottom ends of. the links. as S. It will. be

- noted. that in the last noted positions the r ghthand sash J has reached substantially its. uppermost position, and that the left hand SaSlI A hasremained practically stationary; thechain 6yielding. slightly downwardly andztothe rightso asto prevent any substantial movement of thesash at theleft'. The other positions of the sash asthermo'vementv of the chain continues in'the same dimotion are indicated as; rightwhand sash J;

andlink K.,-left hand sash as M andlinkly, and the juncture of the two links at the chain as T; The next-position shows both sashin the maximum ope'nposition, asright handsash J. link. N, left hand sash" P, and

link .0. and the .junctureof the two links at theicha-in as U; i

: Upona-continued movement of the chain 6' in"counteiaclockwise direction, the lower ends of the links 3 andl3 are; moved downwardly and towardthe left. Such moventi'ent-servesto close the sash at the right,

uih ile the link. at the left merelyswingswith respect to the sash at that sideiwithou't matei' ially chang-ingi the position; of the sash. Upon the furthenmovement of the chain; the lower endsofthe links are moved downwardly and toward-the right, serving'to close the sash at'fthe-leftwhile keeping the sash at the right substantially closed. Since the operating mechanism is sirm'la at itsopposite sides, it is capable of oper-' ating to equal advantage in either direction. I

As will be readily understood, when the chain 6 is driven in clockwise direction, the sash or section at the left is opened first, followed by the opening of the sash at the right. Upon continued movement in such clockwise direction, the sash at the left is closed first, followed by the closing of the sash at the right. a 7

It will be understood also tion, they may be closed by movement of the chain 6 in either direction regardless of the direction in which the chainwas moved for opening them. h

By the use ofmy improved mechanism, either sash can be opened to precisely the desired extent with the other sashentirely closed or substantially, so. In like manner, either sash can be opened toprecisely the desired extent with the other sash in its fully opened position. When it is desired to have both sections open at the same time, with both in fully opened position or with one in fully opened position and the other only partially opened, the mechanism can be operated for opening the sash at either side first as may be desired. this depending entirely upon the direction in which the chain 6 is moved for effecting the opening operation.

While I prefer to employ a construction substantially as shown in the drawing and as above described, I wish to have'it understood that I do not limit the invention tothe form shown. except so far as certain of the claims may be specifically so limited, since it is evident that changes might well be made without departing from thespirit of my in vention.

I claim:

1; A ventilating construction, comprising in combination a supporting structure having an opening therein, a swingingly-mounted section adapted to close said opening, a flexible member in the form of a loop, means for'supporting said memberv in vertically disposed position at spaced points therealong and for moving it about the supports, and a link connected at its lower end with said flexible member and at its upper end with said swingingly-mounted section adapt ed in one position of the flexible member to support the section directly from the flexible member in partially opened position and in another position of the flexible member to hold the section in closed position. i 2. A ventilatingconstruction, comprising in combination a supporting structure having an opening therein, a swingingly-mounted section adapted to close said opening, a flexible member in the form of a loop. means for supporting said flexible member at spaced. points therealong and for moving it about the supports, and a link connected with said flexible member and said swingingly-mounted section adapted by substantially half a revolution of the flexible member in one direction to open said section and by the succeeding half revolution in the direction to close said section.

3. A ventilating construction, comprising in combination a supporting structure havi a ing-an opening therein, a swingingly-mountthat with both sections standing intheir fully openedposiing it about .the supports, and a link connected with said flexible member and with said swingingly-mounted section adapted by substantially a quarter of a revolution same 01 the flexible member in one direction to open said section, by a succeeding quarter of a revolution to hold the section in substantially unchanged position, by the succeeding'quarter' of a revolution to move the section to closed position, andbythe succeeding quarter of a revolution torna-intain the section in closed position.

4. A ventilating construction, comprising in combination a supporting structure hav-' ing an opening therein, a pair of swinginglymounted sections adapted to close saidopen ing, a flexible member in the form of a loop,

I means for supporting said member at spaced points therealong and for moving itabout the supports, and linksconnected with said flexiblemember and the respective sections adapted inone position of the flexible memher to hold both sections closed, in another position toholdfone section open and the other closed, in another position to hold both 7 sections closed, and in a fourth position to hold the first-opened section closed and the other sectionopen. Y

5. A ventilatingconstruction, comprising in combination a supporting structure-haw ing an opening therein, a section hingedly mounted at its upperend adapted in diagonal position to close said opening, a flexible member in the form of a loop, a plura-lity of supporting means revolubly mounted on horizontal axes in spaced relation to each other for supporting said flexible member andfor moving it thereabout, and a link connected with said flexible member and with said swingingly mountedsection adapted to be moved upwardly by the movement of said flexible member about its supports for raising the section to its opened position.

6. A ventilating construction, comprising in combination a supporting structure having an opening therein,a section hingedly mounted at its upper end adapted'indiagonal position to close said opening, a flexible member in the form of a loop, a plurality of supporting means revolubly mounted on horizontal axes in spacedrelationto each other for supporting said flexible member and for moving it thereabout, and a link connected with said flexible member and with said swingingly mounted section adapted by a portion of the movement of the flexible member to move the section toits open position, by the next succeeding portion of the movement of the flexible member in the same direction to hold the section in raised position substantially without change, by the next succeeding portion of the movement in the same direction to close the section, and by the remaining portion of a complete 10 cycle of movement to hold the section substantially closed;
